● Each smart cooling product supports a maximum of twelve T/H sensors outside the
cabinet, including a maximum of six cold aisle T/H sensors and six hot aisle T/H sensors.
● It is recommended that the total length of the cable required for the T/H sensors
outside the cabinet be less than or equal to 150 m. If the cable length is greater than
120 m, obtain 12 V DC power from the site to supply power to the T/H sensors that are
120 m or further away from the cabinet. Ensure that the input voltage of each T/H
sensor ranges from 9 V to 16 V.
● The T/H sensors outside the cabinet must be connected to a Category 5E cable or a
network cable with higher specifications. Otherwise, the power supply voltage of the
T/H sensors may be insufficient due to large impedance of the network cable. When the
voltage is less than 9 V, the T/H sensors cannot work properly.
